Show moreThe WPA Block Profiles of the San Francisco Department of City Planning Records contains original block drawings prepared for construction of a 3-dimensional wood model of the city. In 1938, the City Planning Commission sponsored this work. The relief map, called the WPA Sectional Model, was built by federal Work Projects Administration workers. The block drawings sometimes include the draftsman's name. A map, "Key to the WPA Sectional Model," is included. Generally, only one block appears on a sheet. The scale of the maps, as well as the model, is 1 inch = 100 feet, both horizontally and vertically. The drawings include building footprints, or outlines of buildings at ground level, and block-long street elevations at appropriate grade. The official grade elevation is stated in feet at corners, or where mid-block changes occur. Street addresses, lot sizes, and building uses are not given. The profiles can be used to determine a building's footprint and relative height in stories can be determined.
